Pre-operational System Testing
69
DCB, DCFCB and DCFCTB Models
indicated, follow up by load testing each battery with an automotive type battery
load tester (180 Amp load recommended).
6. Turn AC power on by connecting F1 and F2 and turning on the service
disconnect switch.
Battery Charger Voltage Measurement
To measure the output voltage of each charger, it must be connected to a battery.
Since the battery’s state of charge affects the output voltage of the charger, the
measured voltages varies. Use a digital multi-meter to measure each battery charger
individually (refer to the test points given in the Battery Voltage Measurement
section on page 68). The output voltage of each battery charger should be between
13.4 VDC and 13.6 VDC when connected to a fully charged battery.
2001TRB Transformer/Rectifier testing (optional)
1. With the AC service turned on, measure for 46.0 VDC, +/- 0.5 VDC between
K3-3 and chassis ground (refer to Figure 18 Transformer Rectifier Wiring to
Control Unit).
2. Confirm that K3 is energized.
3. Shut off the service disconnect and confirm that K3 de-energizes.
Manual Siren Activation
Manually depress each function button and confirm correct siren operation. Refer to
the controller programming and test data sheet (shipped with controller) for siren
function details.
Land Line Siren Activation (optional)
Confirm that the user-supplied telephone control relay provides each appropriate
remote function input with a momentary contact closure (1 second nominal) and
observe proper siren activation. Refer to the Control Board Power Input section on
page 29 for details on interfacing and wiring.
Transceiver Audio Level Adjustments and VSWR Testing
Due to the test equipment requirements and RF control systems knowledge required
to perform the following controller testing, only a qualified two-way Radio Service
Technician should conduct the following test steps.
To ensure reliable radio controlled siren operation, the following testing must be
conducted upon initial controller installation. For the following steps, connect the
Communications Service Monitor to the RF bulkhead mounted on the bottom side of
the control cabinet.
